Description

本発明は、例えば、第一部材と第二部材との基端部同士を枢着して、双方が重合した閉塞状態から第一部材に対して第二部材を所定角度（例えば１８０度近く）まで回動した開放状態に開閉できるヒンジ装置、並びにこのヒンジ装置を用いた例えば携帯電話やノート型パソコンなどの電子機器に関するものである。   In the present invention, for example, base ends of the first member and the second member are pivotally attached to each other, and the second member is placed at a predetermined angle (for example, close to 180 degrees) with respect to the first member from the closed state in which both are superposed. The present invention relates to a hinge device that can be opened and closed in an open state that is rotated up to an angle, and an electronic device such as a mobile phone or a notebook computer using the hinge device.

本出願人は、国際公開されたＷＯ ００／５０７８０公報に示すように、ワンタッチで本体部（例えば上面に操作部を備えた筐体）に対して重合部（例えば伏面にディスプレイ部を備えた筐体）が開放するヒンジ装置（以下、従来例）を開発した。   As shown in International Publication WO 00/50780, the present applicant is provided with a superposition part (for example, a display part on the lower surface) with respect to a main body part (for example, a casing having an operation part on the upper surface) with one touch. We have developed a hinge device (hereinafter, a conventional example) that opens the housing.

この従来例では、折り畳みタイプの携帯電話に適用した場合、このヒンジ装置に設けた解除操作部（押込ボタン）を指で押すだけで閉塞付勢されている例えばディスプレイ部が自動的に一挙に開放回動することになる。   In this conventional example, when applied to a folding-type mobile phone, the closing operation unit (push button) provided on the hinge device is urged to close by simply pressing it with a finger. For example, the display unit is automatically opened all at once. It will turn.

ＷＯ ００／５０７８０公報WO 00/50780

この自動開放機能を果たす従来例は、閉塞付勢機能を果たしながらも、ワンタッチで自動開放する構造を実現するものであるが、ワンタッチで例えば重合部が一挙に開放するため、その勢いによりしっかり手で支えていないと、即ち携帯式電話においては、例えば本体部をしっかり持っていないと、手から落下してしまうおそれがある。   The conventional example that achieves this automatic opening function realizes a structure that automatically opens with one touch while fulfilling the blocking biasing function. However, for example, the overlapping part is opened at once with one touch. If the mobile phone is not supported by the mobile phone, that is, for example, if the main body is not firmly held, the mobile phone may fall from the hand.

具体的には、従来例は、前述した押込ボタンが本体部と重合部との枢着部の端部に突出した状態（枢着部及びヒンジ装置の同一軸延長線上）に設けられているが、この押込ボタンを押した際、この押込ボタンを押す指が回転する支点となり、重合部が開放した際の勢いで本体部もつられて回転することで落下してしまう場合がある。   Specifically, in the conventional example, the above-described push button is provided in a state where the push button protrudes from the end of the pivoting portion of the main body portion and the overlapping portion (on the same axis extension line of the pivoting portion and the hinge device). When the push button is pushed, a finger that pushes the push button becomes a fulcrum for rotation, and there is a case where the body part is entangled and rotated by the momentum when the overlapping part is opened.

この問題は、重合部の開放を良好にすべく開放付勢バネとして強いバネが使用される、薄型化の傾向にある本体部が持ちにくい（本体部の側部の面積が狭い）、大型ディスプレイ部の採用による重合部の大型化（開放した際の遠心力の増加）など、近年、落下し易い条件が増えてきていることから益々増加傾向にある。   The problem is that a strong spring is used as an open biasing spring to improve the opening of the overlapping part, and the main body tends to be thinner (the area of the side of the main body is small), a large display In recent years, conditions for easy dropping have increased, such as an increase in the size of the polymerized portion (increase in centrifugal force when opened) due to the adoption of the portion.

本発明者は、前述した自動開放機能を果たすヒンジ装置に更なる実験・研究を重ね、その結果、極めて商品価値の高い画期的なヒンジ装置並びにヒンジ装置を用いた携帯式電子機器を開発した。   The inventor conducted further experiments and research on the above-described hinge device that performs the automatic opening function, and as a result, developed an innovative hinge device with extremely high commercial value and a portable electronic device using the hinge device. .

添付図面を参照して本発明の要旨を説明する。   The gist of the present invention will be described with reference to the accompanying drawings.

また、請求項４記載の発明においては、前述のような作用効果を発揮する画期的な電子機器を提供できることとなる。 In the invention according to claim 4 , it is possible to provide an epoch-making electronic device that exhibits the above-described effects.

好適と考える本発明の実施形態を、図面に基づいて簡単に説明する。   Embodiments of the present invention considered to be suitable will be briefly described with reference to the drawings.

本発明は、第一部材１に設けた開放操作部４を操作して回動付勢部３を作動させると、第二部材２はこの回動付勢部３により回動付勢され、第一部材１に対して重合した閉塞状態から開放状態となる。   In the present invention, when the rotation urging unit 3 is operated by operating the opening operation unit 4 provided on the first member 1, the second member 2 is urged to rotate by the rotation urging unit 3. From the closed state polymerized with respect to the one member 1, the open state is set.

ところで、本発明は、前記第二部材２を前記第一部材１に対して重合した閉塞状態から開放状態となるまで回動付勢する回動付勢部３と、この回動付勢部３が作動するよう操作する開放操作部４に付与した操作動力を前記回動付勢部３に伝達する動力伝達部５とを有し、前記開放操作部４を前記第一部材１の側部にして前記第二部材２との枢着部６よりも基端側の部位に設けた構成であり、この構成から、前述した従来例のような第二部材２の開放時に落下させてしまうことを可及的に防止することができる。   By the way, the present invention includes a rotation urging unit 3 that urges the second member 2 to rotate from the closed state in which the second member 2 is superposed on the first member 1 to the open state, and the rotation urging unit 3. And a power transmission unit 5 that transmits the operating power applied to the opening operation unit 4 that operates to actuate to the rotation biasing unit 3, and the opening operation unit 4 is a side portion of the first member 1. The second member 2 is provided at a position closer to the base end side than the pivoting portion 6, and from this configuration, the second member 2 is dropped when the second member 2 is opened as in the conventional example described above. It can be prevented as much as possible.

即ち、本発明は、回動付勢部３を作動するよう操作する開放操作部４を該回動付勢部３と離れた位置から動力伝達部５を介して確実に操作し得る構成であり、よって、この開放操作部４を第一部材１の側部にして前記第二部材２との枢着部６よりも基端側の部位に設けることができる。   That is, the present invention has a configuration in which the opening operation unit 4 that operates to operate the rotation urging unit 3 can be reliably operated via the power transmission unit 5 from a position away from the rotation urging unit 3. Therefore, the opening operation portion 4 can be provided on a side portion of the first member 1 at a position closer to the base end side than the pivot attachment portion 6 with the second member 2.

従って、前述した従来から提案されるものと異なり、開放操作部４を操作する指が第一部材１の回転支点となる部位から離れた位置で操作し得る構造にできるから、この開放操作部４を操作して第二部材２が回動付勢部３の回動付勢により開放してその衝撃が第一部材１に掛かった際、第一部材１を回転させてしまうことなく該第一部材１を堅固に持った状態が得られることになり、よって、落下させてしまうことを可及的に防止することができる。   Therefore, unlike the above-described conventional proposal, the opening operation unit 4 can be structured such that the finger that operates the opening operation unit 4 can be operated at a position away from the portion that serves as the rotation fulcrum of the first member 1. When the second member 2 is released by the rotation urging force of the rotation urging portion 3 and the impact is applied to the first member 1, the first member 1 is not rotated. A state in which the member 1 is firmly held can be obtained, and therefore, it can be prevented from dropping as much as possible.

また、本発明は、動力伝達部５は、前記開放操作部４の操作動力を受ける動力受け部７ａを力点として擺動する擺動体７の作用点が前記回動付勢部３が作動するよう作用する作用部７ｂとして機能するように設けて構成されており、梃子の原理を利用して少ない力で作動させることができ、第一部材１に対する第二部材２の開放操作が簡易且つ楽に行えることになり、しかも、この点においても落下させてしまうことが可及的に防止されることになる。   Further, according to the present invention, the power transmission unit 5 acts so that the rotation urging unit 3 operates at the point of action of the sliding body 7 that swings with the power receiving unit 7 a that receives the operation power of the opening operation unit 4 as a power point. It is provided and configured so as to function as the acting portion 7b, and can be operated with a small force by utilizing the principle of the lever, and the opening operation of the second member 2 with respect to the first member 1 can be performed easily and easily. Moreover, it is prevented as much as possible from dropping at this point.

本発明の具体的な一実施例について図面に基づいて説明する。   A specific embodiment of the present invention will be described with reference to the drawings.

本実施例は、ヒンジ装置を用いた電子機器として図１に示すような携帯電話に本発明を適用したもので、回路基板，電源などの電子部品をケース内に内装すると共に、上面１Ａに数字キーやファンクションキーなどを配列したキーボード機能を果たす操作部11を備えた板状の本体部（筐体）を第一部材１とし、この本体部１に重合して操作部11を覆う略同形状のディスプレイ部12を設けた板状の重合部（筐体）を第二部材２とし、この本体部１と重合部２とを起伏回動自在にヒンジ装置により軸着連結した構成としている。   In this embodiment, the present invention is applied to a mobile phone as shown in FIG. 1 as an electronic device using a hinge device. Electronic components such as a circuit board and a power source are housed in a case, and numbers are displayed on an upper surface 1A. The first member 1 is a plate-like main body (housing) having an operation section 11 that performs a keyboard function in which keys, function keys, etc. are arranged. The main body section 1 is overlapped to cover the operation section 11. The plate-like overlapping portion (housing) provided with the display portion 12 is used as the second member 2, and the main body portion 1 and the overlapping portion 2 are pivotally connected to each other by a hinge device so as to be pivotable.

具体的には、重合部２を回動付勢する回動付勢部３を具備し、この回動付勢部３は前記本体部１に設けた開放操作部４の操作により作動して前記第二部材２を前記第一部材１に対して重合した閉塞状態から開放状態となるまで回動付勢するように構成されている。   Specifically, a rotation urging portion 3 that urges the overlapping portion 2 to rotate is provided, and the rotation urging portion 3 is operated by an operation of an opening operation portion 4 provided in the main body portion 1 to The second member 2 is configured to be urged to rotate from the closed state in which the second member 2 is superposed on the first member 1 to the open state.

回動付勢部３は、図２，３に図示したように重合部２の基端部に設けられる取付部２ａに嵌着する第一連結体３Ａと、この第一連結体３Ａに対して相対回動自在に連結され本体部１の基端部に設けられる取付部１ａに嵌着する第二連結体３Ｂとを有する。   As shown in FIGS. 2 and 3, the rotation urging portion 3 includes a first connection body 3A that is fitted to a mounting portion 2a provided at a base end portion of the overlapping portion 2, and the first connection body 3A. And a second connecting body 3B that is connected to the mounting portion 1a that is connected to the base end portion of the main body 1 so as to be relatively rotatable.

この第一連結体３Ａの内部には、例えば本出願人が特許公開２００３−２０２０１３にて提案する回動付勢構造（図示省略）が内装されており、第二連結体３Ｂの端部から突出した被押圧部３ａを押圧することで回動付勢構造における回動阻止状態が解除されて作動して、第一連結体３Ａと第二連結体３Ｂを相対回動付勢するように構成されている。   Inside the first connecting body 3A, for example, a rotation urging structure (not shown) proposed by the present applicant in Japanese Patent Publication No. 2003-202013 is housed, and protrudes from the end of the second connecting body 3B. When the pressed portion 3a is pressed, the rotation preventing state in the rotation urging structure is released to operate, and the first connecting body 3A and the second connecting body 3B are urged to rotate relative to each other. ing.

従って、回動付勢部３に設けた被押圧部３ａに対する押し込み操作することで、第一連結体３Ａと第二連結体３Ｂが相対回動し、本体部１に対して重合部２が開放方向に回動することになる。   Accordingly, when the pushing operation is performed on the pressed portion 3 a provided in the rotation urging portion 3, the first connecting body 3 </ b> A and the second connecting body 3 </ b> B are relatively rotated, and the overlapping portion 2 is opened with respect to the main body portion 1. Will rotate in the direction.

また、この回動付勢部３が作動するよう操作する開放操作部４を本体部１に設けるとともに、この開放操作部４に付与した操作動力を回動付勢部３に伝達する動力伝達部５を本体部１に設けている。   Further, an opening operation unit 4 for operating the rotation urging unit 3 is provided in the main body unit 1, and a power transmission unit for transmitting the operation power applied to the opening operation unit 4 to the rotation urging unit 3. 5 is provided in the main body 1.

具体的には、この動力伝達部５は、前記開放操作部４の操作動力を受ける動力受け部７ａを力点として擺動する擺動体７の作用点が前記回動付勢部３が作動するよう作用する作用部７ｂとして機能するように設けて構成されている。   Specifically, the power transmission unit 5 acts so that the rotation urging unit 3 operates at the point of action of the sliding body 7 that swings with the power receiving unit 7a receiving the operation power of the opening operation unit 4 as a power point. It is provided and configured to function as the acting portion 7b.

開放操作部４は、図２〜４に図示したように適宜な金属製の部材で形成したスライド体４Ａを、本体部１に設けた配設部１ｂにスライド自在に設けて構成されており、本体部１の側部１Ｂ（側面）にして重合部２との枢着部６となる取付部１ａよりも基端側の部位に設けた開口部１ｃからスライド体４Ａの一部が突出する状態に設けられている。   As shown in FIGS. 2 to 4, the opening operation unit 4 is configured by slidably providing a slide body 4 </ b> A formed of an appropriate metal member on an arrangement unit 1 b provided on the main body unit 1. A state in which a part of the slide body 4A protrudes from an opening 1c provided on a side portion 1B (side surface) of the main body portion 1 and a base end side portion relative to the attachment portion 1a serving as a pivot portion 6 with the overlapping portion 2. Is provided.

このスライド体４Ａは、本体部１を持つ手の指（例えば親指）で本体部１の前後方向（長さ方向）にスライドさせることができる。   The slide body 4A can be slid in the front-rear direction (length direction) of the main body 1 with a finger (for example, thumb) of the hand holding the main body 1.

また、スライド体４Ａは、前方向にスライドさせた際に戻り付勢が生じるように構成されている。   Further, the slide body 4A is configured to generate a return bias when it is slid in the forward direction.

具体的には、スライド体４Ａは、図２，３に図示したように配設部１ｂに設けられる付勢体10の付勢に抗して前方向にスライドするように構成されている。   Specifically, the slide body 4A is configured to slide forward against the urging force of the urging body 10 provided in the arrangement portion 1b as shown in FIGS.

この付勢体10は、前記スライド体４Ａを該スライド体４Ａのスライドに連動する後述する擺動体７に対して離反する方向に付勢するものである。   The urging body 10 urges the slide body 4A in a direction away from a sliding body 7 (to be described later) interlocked with the slide of the slide body 4A.

また、スライド体４Ａの先端部には傾斜部４ａが形成されており、スライド体４Ａを付勢体10の付勢に抗してスライドさせた際、この傾斜部４ａを擺動体７の動力受け部７ａが乗り上がることで擺動体７を擺動させることになる。   An inclined portion 4a is formed at the tip of the slide body 4A. When the slide body 4A is slid against the urging force of the urging body 10, the inclined portion 4a receives the power of the peristaltic body 7. As the part 7a rides on, the moving body 7 is swung.

従って、このスライド体４Ａにおける付勢体10の戻り付勢に抗したスライド操作により擺動体７の動力受け部７ａに該スライド体４Ａの操作動力を付与し得ることになる。   Accordingly, the operation power of the slide body 4A can be applied to the power receiving portion 7a of the peristaltic body 7 by the slide operation against the return bias of the biasing body 10 in the slide body 4A.

擺動体７は、図２，３に図示したように適宜な金属製の部材で形成した棒状体であり、本体部１の配設部１ｂにしてスライド体４Ａと回動付勢部３との間の位置に軸体13を介して回動自在に設けられている。   The sliding body 7 is a rod-shaped body formed of an appropriate metal member as shown in FIGS. 2 and 3. The sliding body 7 serves as an arrangement portion 1 b of the main body portion 1 and includes a slide body 4 </ b> A and a rotation biasing portion 3. It is rotatably provided at a position between them via a shaft body 13.

また、この擺動体７の一端部はスライド体４Ａの傾斜部４ａの近傍位置に配され、他端部は回動付勢部３の被押圧部３ａの近傍位置に配されており、この擺動体７における枢着部７ｃ（支点）を境とした一端部は開放操作部４の操作動力を受ける動力受け部７ａ（梃子の原理で言う力点）として機能し、他端部は前記回動付勢部３が作動するよう作用する作用部７ｂ（梃子の原理で言う作用点）として機能する。   Further, one end portion of the swinging body 7 is disposed in the vicinity of the inclined portion 4a of the slide body 4A, and the other end portion is disposed in the vicinity of the pressed portion 3a of the rotation biasing portion 3. One end portion of the body 7 with the pivoting portion 7c (fulcrum) as a boundary functions as a power receiving portion 7a (power point in the principle of the lever) that receives the operating power of the opening operation portion 4, and the other end portion is attached with the rotation. It functions as the action part 7b (the action point said by the lever principle) which acts so that the urging part 3 operates.

従って、開放操作部４に係るスライド体４Ａをスライドさせた際、該スライド体４Ａの傾斜部４ａを擺動体７の動力受け部７ａが乗り上がることで該擺動体７は擺動し、この擺動体７の擺動により該擺動体７の作用部７ｂは回動付勢部３の被押圧部３ａを押圧することになる。   Therefore, when the slide body 4A related to the opening operation unit 4 is slid, the peristaltic body 7 is swung by the power receiving part 7a of the peristaltic body 7 riding on the inclined part 4a of the slide body 4A. 7, the action portion 7 b of the sliding body 7 presses the pressed portion 3 a of the rotation urging portion 3.

以上のように、前述した構成のスライド体４Ａと擺動体７とで動力伝達部５が構成されている。   As described above, the power transmission unit 5 is configured by the slide body 4 </ b> A and the sliding body 7 having the above-described configuration.

以上の構成からなる本実施例に係るヒンジ装置における本体部１に対する重合部２の開放操作について説明する。   The opening operation of the overlapping portion 2 with respect to the main body portion 1 in the hinge device according to the present embodiment having the above configuration will be described.

先ず、図４，５に図示した状態から開放操作部４に係るスライド体４Ａを本体部１の前方向（長さ方向）にスライドさせる。この際、付勢体10の戻り付勢に抗しながらのスライド操作となる。   First, the slide body 4A according to the opening operation unit 4 is slid in the forward direction (length direction) of the main body unit 1 from the state illustrated in FIGS. At this time, the slide operation is performed while resisting the return bias of the biasing body 10.

このスライド体４Ａのスライドに際して該スライド体４Ａの傾斜部４ａを擺動体７の動力受け部７ａが乗り上がると、該擺動体７に設けた作用部７ｂが回動付勢部３の被押圧部３ａを押圧する（図６，７参照）。   When the slide body 4A slides, when the power receiving portion 7a of the sliding body 7 rides on the inclined portion 4a of the sliding body 4A, the action portion 7b provided on the sliding body 7 becomes the pressed portion of the rotation biasing portion 3. 3a is pressed (see FIGS. 6 and 7).

Since the overlapping portion 2 is released by the rotation biasing force of the rotation biasing portion 3 and the impact is applied to the main body portion 1, the main body portion 1 is not rotated without being rotated. Since the state where the left and right side portions of the portion 1 are firmly held is obtained (because it is prevented as far as possible from separating the first member 1), the first member 1 and the second member 2 It is possible to prevent as much as possible that the casing made of is dropped.

また、本実施例は、動力伝達部５は、前記開放操作部４の操作動力を受ける動力受け部７ａを力点として擺動する擺動体７の作用点が前記回動付勢部３が作動するよう作用する作用部７ｂとして機能するように設けて構成されており、梃子の原理を利用して少ない力で作動させることができ、第一部材１に対する第二部材２の開放操作が簡易且つ楽に行えることになり、しかも、この点においても落下させてしまうことが可及的に防止されることになる。   Further, in this embodiment, the power transmission unit 5 operates such that the rotation urging unit 3 operates at the point of action of the sliding body 7 that swings with the power receiving unit 7 a receiving the operation power of the opening operation unit 4 as a power point. It is configured so as to function as the acting portion 7b that acts, and can be operated with a small force using the principle of the lever, and the opening operation of the second member 2 relative to the first member 1 can be performed easily and easily. In addition, it is prevented as much as possible from dropping at this point.

また、本実施例は、回動付勢部３に設けた被押圧部３ａに対する押し込み操作により作動するように回動付勢部３は構成されており、擺動体７の擺動により被押圧部３ａを押圧する作用部７ｂを擺動体７に設けたから、簡易な構造で確実に回動付勢部を作動させることができることになる。   Further, in this embodiment, the rotation urging portion 3 is configured so as to be operated by a pressing operation on the pressed portion 3 a provided in the rotation urging portion 3, and the pressed portion 3 a is moved by the peristaltic movement of the sliding body 7. Since the actuating portion 7b that presses is provided on the peristaltic member 7, the rotation urging portion can be reliably operated with a simple structure.

また、本実施例は、開放操作部４は付勢体10の戻り付勢に抗して第一部材１の長さ方向にスライド自在に設けられており、この付勢体10の戻り付勢に抗した開放操作部４のスライド操作により動力受け部７ａに該開放操作部４の操作動力を付与し得るように構成されているから、常に回動付勢部３を作動させる為の状態が得られることになる。   Further, in this embodiment, the opening operation unit 4 is provided so as to be slidable in the length direction of the first member 1 against the return bias of the biasing body 10, and the return bias of the biasing body 10 is provided. Since the operation force of the opening operation part 4 can be applied to the power receiving part 7a by the sliding operation of the opening operation part 4 against the above, the state for always operating the rotation urging part 3 is Will be obtained.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。   Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
